-_- i said it 1000 times already ..
You can't counterpunch on clay ... everyone who had played the game and have simple sence of tennis and has common logic knows this ... For instance: Simon , Hewitt ......
and last but not least Murray thrives on his opponents power ! and his swings are short and rely on timing ... THE END/FIN/KONEC ! Deal with it you low tennis IQ-ers

I'd say Ferrer is more of a bigger counterpuncher than Murray, and he does well on clay

He did not grow up on clay, that's a misconception. He spent 2 years in Barcelona. He grew up on hard courts.

With his movement being one of his key strengths, he doesn't do well on clay, because he is unable to slide into his shots. His forehand is also not potent enough to hit through the court on a regular basis. Obviously, confidence goes a long way as well.

Poor movement in contrast with how he is on HCs/grass. Inability to generate many winners. Poor building of points and indecision about where to defend/attack (because his usual counter-punching isn't as effective).
